A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that combines the optics and mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor.
The development of digital image sensors, microprocessors, memory cards, miniaturised devices and image editing software enabled these cameras to offer their users a much wider range of operating options than was possible with the older silver halide technology. [2] [3] This has led to a proliferation of new abbreviations, acronyms and ...
Magic Lantern is a firmware add-on for various Canon digital single-lens reflex (DSLR) cameras and the EOS M. [2] It adds features for DSLR filmmaking and still photography, and is free and open-source. Magic Lantern was originally written for the Canon EOS 5D Mark II [3] by Trammell Hudson in 2009 after he reverse engineered its firmware. [1]
Firmware in the camera, or a software in a raw converter program such as Adobe Camera Raw, interprets the raw data from the sensor to obtain a full-color image, because the RGB color model requires three intensity values for each pixel: one each for the red, green, and blue (other color models, when used, also require three or more values per ...
Research and development continues to refine the lighting, optics, sensors, processing, storage, display, and software used in digital photography. Here are a few examples: 3D models can be created from collections of normal images. The resulting scene can be viewed from novel viewpoints, but creating the model is very computationally intensive.
This is particularly useful if the subject includes dangerous animals (e.g., wildlife); the subject prefers anonymity to being photographed; or else, the photographer's presence is unwanted (e.g., celebrity photography or surveillance photography). Practically all SLR and DSLR camera bodies can also be attached to telescopes and microscopes via ...
